摘要
预应力锚杆与混凝土网格梁的联合加固能够充分发挥锚杆和网格梁的支护作用,广泛应用于加固工程中。依据锚杆和网格梁各自的特点,说明了预应力锚杆网格梁联合支护结构的挡墙加固机制,介绍了框架梁的内力计算方法和锚索的主要参数设计。通过加固实践详细介绍了预应力锚杆网格梁在既有挡土墙加固中设计施工工艺及其施工流程,并取得了良好的工程效果。
In view of the strengthening effect of prestressed anchor and frame beam method, it is widely applied in the reinforement engineering. According to the characteristics of anchor and frame beam, the reinforcing mechanism is discussed elaborately, and the calculation method of frame beam intemal force and main design parameters of anchor are introduced roundly. The design and construction technique of prestressed anchor and frame beam, as well as the practical example and application of the reinforcement in existent retaining wall with satisfactory effect are introduced detailedly in this paper.
